LOW POWER ELECTRIC MOTOR STARTER FOR A COMPRESSOR MOTOR OF A COOLING DEVICE, CAPABLE OF REDUCING COSTS

摘要

PURPOSE: A low power electric motor starter is provided to reduce costs by including a bias resistor connected to a start winding wire of a single phase motor and a PTC(Positive Temperature Coefficient) resistor which is serially connected to a triac.;CONSTITUTION: A lead relay comprises a sensor coil(16a). The sensor coil is connected in parallel with a main winding wire and a start winding wire. The lead relay is magnetically combined in a lead contact(16b,16c). One lead contact is connected to the intermediate position between the triac(14) and a PTC resistor(12). The other lead contact is connected to the gate of the triac.;COPYRIGHT KIPO 2010
